CINCINNATI -- Three days before their full team begins training camp, the Cincinnati Bengals made a pair of roster moves Monday when they signed defensive tackle LaKendrick Ross, a large-in-stature lineman who went without getting selected in the supplemental draft earlier this offseason, and released receiver Alex Neutz.

An undrafted free agent who played college football at Buffalo last season, Neutz went through organized team activities and minicamp this spring before getting cut this week.

Ross took Neutz’s place, the team announced. The moves mean the Bengals still have 89 players on their preseason roster, one shy of the 90-man limit.

Ross' agent, Glen Lansky, told ESPN.com earlier in the day that his 6-foot-5, 365-pound client was joining the Bengals after a successful tryout at Paul Brown Stadium. Aaron Wilson of the National Football Post and the Baltimore Sun first broke news of Ross’ signing.

"He's a big body and a great fit for the Bengals," Lansky said to ESPN.com. "He holds his weight well."

How well does he hold his weight and move with it? There's video on YouTube of the big lineman dunking a basketball.

One of the more intriguing qualities about Ross is the fact that he's a bit of an unproven talent. He only played one year of football in high school and also spent just one season playing in college at Virginia-Lynchburg, a small university that's part of the United States Collegiate Athletic Association. He was eligible for the supplemental draft but went undrafted even after 12 teams attended a pro day workout Lansky coordinated.

After the draft, the goal was to get Ross a tryout with a team that seemed a logical fit, Lansky said. The agent coordinated the workout with the Bengals last week. Cincinnati added Ross in an effort to get another body on the defensive line for training camp as veteran Geno Atkins continues recovering from offseason ACL surgery. The Bengals are hopeful Atkins will be fully healthy by the Sept. 7 opener. If Ross makes the 53-man roster, he would give them added depth and a bigger presence in run-stop and goal-line situations.

At 365 pounds, Ross is 25 pounds heavier than the Bengals' next-biggest player: 340-pound offensive tackle Andre Smith. Listed at 322 pounds on Bengals.com, Domata Peko now is the next heaviest defensive lineman.

Lansky told ESPN.com Ross signed a standard three-year undrafted free agent contract. With it, he joins James Wilder Jr., Ryan Hewitt, Victor Hampton and now seven others in trying to make the team as an undrafted free agent.

Rookies arrived Monday for the Bengals' training camp, which officially begins Thursday when the full squad is assembled.
